访问 Trigger.Apex 测试类中的新值

Question

tl;dr - 如何让测试类等到特定触发器完成更新或插入后再继续测试？

背景

我有一个触发器，它会在创建 Account 对象时创建一个新的 Portal_Content__c 对象，然后将两个记录相互关联（请参阅下面的Account Trigger）。

我还在Portal_Content__c 对象上创建了一个触发器，该触发器在删除记录时触发。删除后，触发器会查找相关的 Account 记录并将其删除（请参阅下面的门户内容触发器）。

我的问题是关于我的门户内容测试类（下面的最终代码块）。当我对帐户记录运行 DML 插入时，帐户触发器 应该使用帐户触发器中创建的门户内容记录填充 a.Portal_Content_Record__c 字段。但是，当我运行 system.debug() 测试时，它显示运行 SOQL 查询时 a.Portal_Content_Record__c 字段为空。我已经能够通过匹配名称搜索门户内容记录来绕过此问题，但我想通过按确切 ID 搜索来使脚本更加健壮。

问题

如何让 Portal Content Test Class 等到 Account Trigger 填充 a.Portal_Content_Record__c 字段后再继续测试？

--代码块--

帐户触发器

trigger AccountHandler on Account (before insert, after insert, after update, after delete) {

    List<Account> alist = Trigger.New;
    List<Account> oldlist = Trigger.Old;

//  Create new Portal Content with same name as Account if Account is record type 'College/University,'
//  then assign newly created Portal Content to 'Portal Content Record' lookup field on new Account
    if(Trigger.isBefore && Trigger.isInsert){

        for(Account a : alist) {

            if (a.RecordTypeId == '012i0000001Iy1H') {
                Portal_Content__c p = new Portal_Content__c(
                    Name=a.Name,
                    RecordTypeId='012i0000001J1zZ'
                );
                insert p;

                a.Portal_Content_Record__c = p.Id;
            }
        }
    }

//  Delete Portal Content record referenced in an Account's 'Portal Content Record' lookup field
//  if the Account is deleted

    if (Trigger.isAfter && Trigger.isDelete){
        for(Account a : oldlist){
            for(Portal_Content__c p : [SELECT ID FROM Portal_Content__c WHERE ID = :a.Portal_Content_Record__c]){
                delete p;
            }
        }

    }

//  After the new Portal Content record has been created, assign the Account ID of the Account that created it
//  to the 'School SFDC ID' field on the new Portal Content record.    
    if (Trigger.isAfter && Trigger.isInsert){
        for(Account a : alist){

            List<Portal_Content__c> plist = [SELECT ID FROM Portal_Content__c WHERE Id = :a.Portal_Content_Record__c];

            for(Portal_Content__c p : plist){
                p.School_SFDC_ID__c = a.Id;
                update p;
            }

        }
    }

//  Prevent more than one Account from being assigned to a single Portal Content record
    if (Trigger.isAfter && Trigger.isUpdate) {
        for(Account a : alist){
            if (a.Portal_Content_Record__c != null){
                List<Account> alist = [SELECT ID FROM Account WHERE Portal_Content_Record__c = :a.Portal_Content_Record__c];
                system.debug('alist: ' + alist);
                if (alist.size() > 1) {
                    a.addError('The Portal Content record you selected is already associated with another School. Please select a different Portal Content record');
                }
            }
        }
    }
}

Answer 1

我已经在我的 Org.请在下面找到我的 cmets。

• 根据您的要求，我有一个触发器，它会在创建 Account 对象时创建一个新的 Portal_Content__c 对象，然后将两条记录相互关联（请参阅下面的 Account Trigger）。
  我看到Account(Portal_Content_Record__c ) 和Portal Content (School_SFDC_ID__c) 之间存在关系。您正在设置Portal_Content_Record__c。但您还需要链接School_SFDC_ID__c 以满足您的要求。请找到以下代码

  trigger AccountHandler on Account (before insert, after insert, after update, after delete) {
  
          List<Account> alist = Trigger.New;
          List<Account> oldlist = Trigger.Old;
  
      //  Create the new Portal Content with the same name as Account if Account is record type College/University,
      //  then assign newly created Portal Content to Portal Content Record lookup field on new Account
          if(Trigger.isBefore && Trigger.isInsert){
  
              for(Account a : alist) {
  
                  if (a.RecordTypeId == '012i0000001Iy1H') {
                      Portal_Content__c p = new Portal_Content__c(
                          Name=a.Name,
                          RecordTypeId='012i0000001J1zZ',
                          School_SFDC_ID__c = a.id
                      );
                      insert p;
  
                      a.Portal_Content_Record__c = p.Id;
                  }
              }
          }
      }
  

• 我看到唯一的问题是 delete 没有被覆盖 PortalContentHandler 因为不符合条件 List<Account> alist = [SELECT ID FROM Account WHERE Id = :p.School_SFDC_ID__c]; 在创建时填充它 门户内容如上点所述。

• 此外，您需要更改您的测试类，因为没有您尝试查询的门户内容数据。在测试类中，您只获得您在那里创建的数据。 AccountHandler 创建的那个不会成为您的测试类的一部分。创建与您在触发器中创建的数据相同的数据。

  @isTest 
  public class PortalContentHandlerTest {
  
  @isTest static void createThenDeletePortalContent(){
      Account a = new 
      Account(Name='deletePortalTest',RecordTypeId__c='012i0000001Iy1H');
      insert a;
      Portal_Content__c p = new Portal_Content__c(
          Name=a.Name,
          RecordTypeId__c='012i0000001J1zZ',
          School_SFDC_ID__c = a.id
      );
      insert p;
      delete p; 
  }
  
  }
